### Abstract

In this expository article, we discuss some fundamentals of well-known matrix partial orders that are closely associated with space preorder on rectangularmatrices. Particularly, we consider partial order defined by space decomposition, star ordering, and minus partial order for our discussion. These relations are closelyassociated with comparison of column spaces and row spaces of matrices. Resultsassociated with selected matrix relation that are known in the literature along withsome interesting observations are put together. At many places, though the proofsof several results are known in the past literature, by part or completely, for betterreading purpose, independent proofs are provided.
